DSP programming with simulink

I'm working with a DSP/FPGA board and I mostly use the Simulink to generate my
models. I compile, I start the simulation on board with the Simulink and my
qestion is: Is it possible programm the DSP with the simulink? When I connect
the board and the simulation starts, the board (connected via ethernet) works
with autonomy, but when i stop the simulation from the simulink the board stops
working. I would to mantain the program running on the DSP. (during the
simulation if I disconnect the eth cable the board doesn't receive the stop call
and it works indefinetly, but this isn't a very smart way to get it) So my
questions are: Is it possible to program the DSP from the simulink without
receive the "stop simulation call"? If it is not possible, the way to go is to
export the project to the Code composer studio?
